To all whom it may concern: I

Be. it known that I, Lewis G. ALLEN, a.

' citizen or" the United'Stst-es, residing at Cincinnati, in the county of Hamilton and State of (line, have invented new and useful Improvements in Combined Water and Air Pum Mocha. ism of which the tollowing is a specification.

' My invention relates to a, system of water distribution in which wster pumped from a source of supply, such as a Well or cistern,

v intoc distributing tank, isloyzrneans of air pressure forced thence through distributing msins to points where and as needed; and its object is to pro'videsn efficient embodiment in one'structure 411? means for deliver- .ing and maintaining thesupply of water and also of air under pressure, to the distribut n'g tank, the details and. incidental purposes offwhioh improvement w1ll,'more fully and at large appear in the following Referrmgnow to the accompanying drawings, in which the parts of the structure devenient access to the wofking' [par-ts,

scribed herein are designated by corresponding reference'numbers, 1 designates the'base l plate, and 2, '3, the-fist front and rear" sides, respectively, of an upright framework supporting the mechanisrm-sdid front and rear sides being tlut webs or plates bolted below to the base plate; and hrdught together at the top with bolt connections to form aprotectinghood, 11, for said :mechsnism, find being detaohsble'above and below for cor; countershaft 5 projects through it journiil bearing on the rear side hot the frame, and is journeled at'its outer end upon it detectuble bracket or pills-r and carries a bend,

pulley (or'geur) 6, normally loose upon the c0untershaft,'but connected rotetively there to by a suituble'clutehd',when desired to operate'thc pump] ll he ,countershaft carries at its projectingen'di-wi'tliin the supporting frame, a spur pinion". 8, through which OHIO, -.gissmnon, BY DIRECT AND Mnsnn JOHNSON, 0F POMEROY, OHIO.

Specification of Letters Extent- Patented July 11,1911.

- power communicated to the pulley 6, is

transmitted by means-of the spur pinion S 'to a gear 9 secured to a short shaft 10, journaled in and through the side 3 of the frame, uboveund'in line with the counter .shaft 5. The gear') is provided with a crank pin 12 adjustable in a radial slot of one of its spokes to lengthen or shorten the length of stroke as shown in Fig. 2.

Upon the base, vertically beneath the' crank shaft 10, and in line with the crank pin, 12, at its extreme upper and lower po- 'sitions, is located the pump head 13 of a lift pump, through which passes a pump rod, 14:. The water lifted by the pump; is discharged outwerdlythrough a lateral extension 15 of the pump head 13, into the distributing tank (not shown) for distribution by air-pressure, in the mode common in such distribution systems, to the points where needed.

The pump rod 14 is detachably connected by means of a removable pin 16 or other suitable fastening, with a cross head 17 and a pitmari 18 connects the cross head with the crank pin 12, whereby the cross head recip- .rocates the pump-rod as the gear 9 is rotated. Secured to a, lateral extension of the cross 'headvislavertical plunger 1.9 operating telescopically with a close sliding fit in s corresponding pump-barrel 20 mounted, as shown, vertically upon the contiguous wall of the frame- 2 the structure serving as a; guide for/the cross head and also as an ai 1 pump. For its letter function, suitob e check valves are provided in a valve casing 21, to enable; the air pump to draw infuir on its down stroke, and force it through a pipe 22, into the Water discharge conduit 15, whereby aslwater is lifted from the well or cistern and forced into the distributing tank, a given quantity of airris likewise forced into the said tsnlc- A relief gcock 23 is attached to the .valve czising so that the air ,pump may continue its operation without forcing airinto the distributingtank; 51nd likewise, when desirable to operate the air pump alone, Without the water pump,- the pump rod 14 may-be detached by withdrawing its pin 1-6.

. QThe operation of the device is sufiiciently apparent from the foregoing description.

in'cognpactform,,and arranged to be operated by the same immediate driving mecha- It. willilbe seien that the machine embodies also the function of a hood or cover nd also convenlence of man1pulat1'on,. ccessibility for repairs, adjustments to e varying demands of use under a continuous and umform driving force. As'such devices are to be used in dwellings, hotels, etc., where skilled labor and attention is frequently Wanting, it is purposely designed to embody the simplest forms of mechanism, Whose use and manipulation will be obvious and within the capacity of unskilled attendants, and so protected in its frame as to be less liable to accidental injury and derangement, and less likely to cause injury to others. r

I claim as my invention, and desire to secure by Letters Patent of the United States Q 1. In a combined pump of the character indicated, the;combination of a supporting frame, a driven crank-shaft, a pitman concated by. the pitman, and operating the.

Water pump rod connected therewith; an

' air pump barrel secured rigidly to the frame and a plunger attached to the cross head and operating telescopically in said pump barrel as a guide, for the reciprocating crosshead.

2. In a combined pump of the character V indicated, a common base; two vertical Walls, mounted and spaced apart thereon, and brought together and united at the top to constitute a supporting and protecting frame open at the sides; drivin mechanism for the main pump attached to the inner side of one of said Walls and having the shaft bearings in and through the same; and an air pump mounted upon the inner side of the other wall in operative relations withsaid driv-.

ing mechanism.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
